Time is our most precious resource. And unlike other resources - money, for example - you can’t earn more of it. When it’s gone, it’s gone.
Given that we live in an ever-connected, resource-demanding world, you will forever be sought after by others for your time.
In some cases, it’s your obligation to spend time on things you’ve committed to. But in some cases, you have a choice on how much (and when) to spend time on something. This “must do” versus “nice to do” difference applies to work and non-work.
It’s important to recognize that you are ultimately responsible for protecting that time. Family members, friends, colleagues, supervisors, etc., will forever be vying for your time. It’s up to you, and only you, to fiercely protect it.
By “fierce,” I don’t mean being antagonistic, aggressive, or unkind. What I do mean is being proactive, transparent, and clear. No one can protect your time. Only you can do that. No one understands your obligations, commitments, energy, and goals as well you do.
